The effect of the growth medium composition was studied in the case of wheat and barley plants grown in phytotron units. Four soils were created by mixing chernozem with the commercial composts Vegasca and Terra-vita and with sand. The major data of these soils were as follows: bulk density [g · cm-3] 1.47, 1.39, 1.30 and 1.39; pH 7.67, 7.52, 7.39 and 7.64; organic matter content [%] 2.93, 3.42, 5.72 and 2.99; AL-P2O5 [mg · kg-1] 352, 369, 507 and 643; Al-K2O [mg · kg-1] 612, 598, 706 and 1428. At the end of the experiment measurements were made on a number of morphological traits (height, tiller number, leaf number) and yield parameters (spike number, grain number, grain mass). It could be concluded from the results that a 1/5 ratio of compost and 1/5 ratio of sand in the soil used for phytotron experiments is sufficient from the point of view of both soil structure and nutrient content.
